2005 Kia Sorento arm tensioner stripped hole

Hello, I am replacing my timing belt and in the process I managaed to strip the hole where the tensioner arm is screwed in in a 2005 kia sorento. I tried to rethread the hole with a tap and die set but that just worsened the issue. Now I am just wondering if there was a way I could fix that stripped hole through some type of mold? Please let me know what you think, thank you in advance.
